Objective This paper aims at the therapeutic effect aft er the artifitial abortion by employing the TCM periodic treatment with respect to shortening the vaginal bleeding time and accelerating the uterine lining recovery. Methods Sampling 280 cases of artifitial abortion in early pregnancy, the author divides them at random the testing and control groups with each of the membership of 140 cases. Given the Nifuratel perorally same as the control group, the testing group is additionally under the TCM periodic treatment, that is, dosing Chinese medicine with the purpose of eliminating blood stasis,promoting tissue regeneration as well as invigorating the vital energy and nourishing the blood during the 1 to 3 days'postoperation period, giving Chinese medicine with a view of strenthening liver and kidney together with activating vital energy during the 4 to 14 days' postoperation period, instructing Chinese medicine in order to nourish the spleen and kidney as well as regulate Chong and Ren Vessels during the 15 to 25 days' postoperation period perorally and respectivelly. In contrast, the control group is given Xuefuzhuyu Capsules after the whole postoperation period. Results In terms of the time of vaginal bleeding, menstrual recovery and the regenerating condition of the uterine lining, the result (except for 3 cases in testing group and 2 cases in control group quiting the experiment) shows that after treatment (9 days after the abortion) the testing group achieves the effect superior to that of control group (P＜0.01). Conclusion The conclusion is that the TCM periodic therapy is effective in the aspect of shortening the vaginal bleeding time, accelerating the uterine lining recovery and regulating the menstrual circle.

Objective To investigate the means which can prevent postoperative incision infection of elderly patients with obstructive colorectal cancer. Methods Sixty-seven cases of elderly patients with obstructive colorectal cancer adopting surgical treatment were divided into two groups, including experimental group with 37 cases and control group with 30 cases. Put self-made negative pressure drainage tube with side-hole into subcutaneous interspace of abdominal incision of experimental group alter operation, kept continuous negative pressure drainage 7-10 d and pull out the self-made subcutaneous negative pressure drainage tubes till drainage volume decreased obviously. The abdominal wall incisions of the control group were given conventional suture. Results Incision infection occurred in only one case (2.7%) and no incision dehiscence occurred in the experimental group, and incision healing time was (9.36 ± 2.18) d. Incision infection occurred in 7 cases (23.3%) in the control group, of which there were 3 cases (10.0%) of wound dehiscence, incision healing time was (12.25 ±4.06) d. Incision infection rate of the two groups had significant difference (χ2= 6.706,P < 0.05), incision dehiscence rate of the two groups had no significant difference (P 0.05), incision healing time of the two groups had significant difference (t = 6.676, P < 0.05). Conclusion Using the self-made subcutaneous negative pressure drainage tube and keeping it continuous negative pressure drainage after operation can be effective in preventing incision infection of elderly patients with obstructive colorectal cancer, and promote wound healing.

Objective To compare the changes of serum hepcidin,hemoglobin and other indexes of pure hemodialysis and hemodialysis combined with hemodiafiltration in treatment of maintenance hemodialysis patients,and to investigate the effect of hemodialysis combined with hemodiafiltration therapy on serum hepcidin clearance,the improvement of anemia and the relationship between them of maintenance hemodialysis patients.Methods Twenty-two patients with maintenance hemodialysis patients were collected from Shengjing Hosphal Affiliated to China Medical University from January 2015 to February 2017.This study was self-controlled study,before enrollment all patients were given only regular hemodialysis,after enrollment all patients were given hemodialysis combined with hemodiafiltration therapy for 3 months,compared the changes of serum hepcidin,hemoglobin,reticulocyte percentage,ferritin,serum iron,transferrin saturation and EPO of pure hemodialysis(before treatment) and hemodialysis combined with hemodiafiltration treatment for 3 months of patients,and analyzed the correlationship between serum hepcidin and other indexes.Results After hemodialysis combined with hemodiafiltration therapy for 3 months,compared with pure hemodialysis serum hepcidin levels were significantly lower((77.61±3.31) μg/L vs.(89.49±7.87) μg/L,t=9.660,P<0.01),hemoglobin levels were increased((112.73±11.02) g/L vs.(88.32±11.83) g/L,t=-11.957,P<0.01).The correlations between serum hepcidin and other indexes show that serum hepcidin and hemoglobin and ferritin were related,serum hepcidin was negatively correlated with hemoglobin(r=-0.851,P<0.01)and positively correlated with ferritin(r=0.385,P<0.05),and found no correlations between hepcidin and reticulocyte percentage(r=-0.151,P=0.328),serum iron(r=0.123,P=0.427),transferrin saturation(r=0.211,P=0.170) and EPO(r=-0.173,P=0.261).Conclusion To compare with pure hemodialysis,hemodialysis combined with hemodiafiltration therapy can more effectively remove hepcidin and improve anemia,and they are related.

BACKGROUND: The pathway of cholinergic nerve also with rich opium receptor in the septum-hippocampus areas is an important part for spatial learning memory. There is study that naloxone, an antagonist of opium receptor, can relieve the inhibition of activity of cholinergic neuron caused by opioid peptides in the medial septum and hippocampus, promote the release of acetylcholine (Ach)into synaptic cleft, and improve the impairment of spatial memory.OBJECTIVE: To investigate the intervention effect of naloxone on impairment of spatial working memory of rats induced by scopolamine, a blocker of cholinergic muscarinic receptor.DESIGN: A randomized and controlled trial taking experimental animals as subjects.SETTING: Geriatric Department of Wuzhongpei Memorial Hospital at Shunde District of Foshan City.MATERIALS: The experiment was completed from 2003 to 2004 at the Experimental Animal Center of Medical School of Shantou University. A total of 21 SD rats of clean grade were at random divided into three groups:normal group, scopolamine group and naloxone group (scopolamine and naloxone), with 7 in each group. Build up of Morris water maze: A circular rubber pool, 2 m diameter and 55 cm height, with 30 cm depth of water at20℃-22℃, was built up. At the center of its southeast quadrant, a cylinder platform installed, which was 12 cm in diameter and 1.5 cm below the water surface, the only place for rats to escape death. The water of the pool was covered with bits of white polythene. In the house, there were light tubes, windows and tables in fixed place served as the outside cues of the pool. On the four walls of the pool, there were several randomly-hung and eye-catching markers as inside cues.METHODS: Medicines were intraperitoneally given 30 minutes before the experiment for rats in each group, scopolamine 0.4 mg/kg and naloxone 3mg/kg in two treatment groups, the equal volume saline in normal group.Then escape latencies of rats were recorded for two successive trials through a delayed-matching\task in self-made Morris water maze. After the Morris water maze examination, all rats were put to death, the tissue of left brain was selected, conventionally treated and sliced. The expression level of cholinacetyltranslase (ChAT) in areas of hippocampus and prefrontal lobe were quantitatively assayed by immunohistochemistry and the computerized image technique. At the same time, the tissue of right brain in two rats of each group was selected, the hippocampus was immediately freed, and the change of CAI region of the hippocampus observed with electron microscope.trastructure of CA1 region of hippocampus in rats.cies of two successive trials were very significantly different in normal group[(46.4±17.7)vs (13.4±8.2)s, t =7.32, P＜ 0.01], and significantly different in naloxone treatment group[ (27.9±14.3)vs (9.0±3.8)s, t=3.19, P＜ 0.05], but not pression of ChAT in pyramidal cells in CA1 and CA3 regions of hippocampus and in neurons of prefrontal cortex of three groups was not different statisticalhippocampus in all groups was normal; However, the ultrastructure of the neuron synapsis was abnormal obviously in scopolamine group: The synaptic vesicles were markedly different in size; the vesicles obviously gathered in the part of presynaptic membrane with an enhanced density, and large and sparse in the distal part. Both presynaptic and postsynaptic membranes were indistinct and fused, synaptic cleft not clear, and postsynaptic dense materials not homogeneous, indistinct and without clear borderline.CONCLUSION: Scopolamine could impair the power of spatial working memory in rats. Naloxone could promote great release of Achin neuron synaptic vesicles into synaptic clefts, and increase the density of postsynaptic dense materials, relieve the inhibition of opioid peptide to cholinergic neuron activity in the medial septum and hippocampus, and could improve space memory injury.

[Objective]To test and prove the mushroom shaped surface prosthesis of femoral head not only can be a weight-bearing device,but also could reduce stress-shelter and achieve long-term stability.[Method]A simplified three-dimensional model of femoral head was made.And the biomechanics of femoral head were compared by finite element analysis in two states:with and without the replacement.[Result]It showed that the maximum of strees in famoral head was less than 40Mpa,consequently the replacement had sufficient strength to meet its basic function.Furthermore,the prosthesis bear the force both at up part and down.Therefore it reduced stress-shelter.[Conclusion]This prosthesis can achieve immediate and long-term stability.And it provides new ideas for designing the femoral head resurfacing prosthesis.

Objective To investigate the clinical characteristics and related risk factors of infarction secondary to severe traumatic brain injury.Methods 480 traumatic brain injury patients were chosen.Depending on the occurrence of cerebral infarction,patients were divided into TCI groups and non-TCI group,clinical symptoms and signs of TCI group were observed,and its related risk factors was analyzed.Results In 480 cases patients,there were 30 cases of patients with traumatic brain injury secondary to cerebral infarction,the rate was 6.25%.Clinical manifestations included unilateral limb motor and sensory dysfunction,visual dysfunction,language dysfunction,dizziness,headache.10 cases Prognosis were good,6 cases were mild disability,3 cases were severe disability,1 case was plant survival,10 patients died.Univariate analysis showed that the rates of aged ≥50 years,GCS score ＜ 8 points,hernia,hypotension,subarachnoid hemorrhage,large doses of non-dehydrating agent in the TCI group were higher than those of non-TCI group,the differences were statistically significant (x2 =12.311 3,14.725 4,19.867 8,5.296 9,9.242 6,11.713 6,all P ＜ 0.05).Logistic multivariate analysis showed that age ≥50 years,GCS score ＜ 8 points,hernia,cerebral hypotension were important risk factors.Conclusion Brain injury patients with cerebral infarction secondary to clinical manifestations have some characteristics.Age ≥50 years,GCS score ＜ 8 points,hernia,hypotension are important risk factors.

Objective To observe differences between repeat and written response in speech recognition tests of short Mandarin monosyllable lists. Methods 12 normal-hearing subjects were tested by 6 short monosyllabic lists. The subjects should repeat and write down.the contents of the tests at the same time, the tester monitors au-rally and records the subjects' reactions. The speech recognition scoring error under different responses at different presentation levels could be obtained by comparing the records of the subjects with the tester. Results The speech recognition scoring of repeat and written response were highly correlated with each other (P<0.01). However, 19(26.4%) out of 72 pairs of test records were inconsistent. The error range of them was from -5% to 10%. When the presentation level was 5 dB HL, the difference among the speech recognition scoring was significant statistically, but not significant when the presentation level at 20, 15, 10 and 0 dB HL. Conclusion The test results of speech audiometry are impacted by different respond methods. In the open-set test, it's supposed that the subjects should make notes while repeating the contents of the tests, then compare with the aural monitoring records of the tester to keep the reliability of the test.

Objective To detect serum level of anti-M-type phospholipase A2 receptor (PLA2R) antibody in elderly patients with idiopathic membranous nephropathy (IMN) and to explore its clinical significance in IMN disease.Methods A total of 134 patients with renal biopsy-proved glomerular diseases were enrolled in this study,including 42 elderly cases with IMN,45 non-elderly cases with IMN,19 elderly cases with minimal change nephropathy (MCN),12 elderly cases with IgA nephropathy (IgAN),8 elderly cases with hepatitis B-associated membranous nephropathy (HBV-MN) and 8 elderly cases with focal segmental glomerulosclerosis (FSGS).Western blotting was used to detect serum anti-PLA2R antibody and the correlation of anti-PLA2R antibody with laboratory parameters in elderly IMN patients was analyzed.Results The elderly and non-elderly patients with IMN showed that the positive rate of anti-PLA2R antibody was 71.4％ and 73.3％,respectively (P＞ 0.05).The positive rate of anti-PLA2R antibody in elderly IgA nephropathy,HBV-MN and MCN patients was 16.7 ％,12.5％ and 5.3％ respectively.Anti-PLA2R antibody was not detected in serum from elderly FSGS patients.The positive rates of serum anti-PLA2R antibody were significantly higher in both elderly and non-elderly IMN patients than in elderly patients with secondary MN and other types of glomerlonephritis (P ＜ 0.01).Furthermore,anti-PLA2R autoantibody level was positively correlated with 24-hour urine protein level and negatively correlated with the concentration of serum albumin in elderly patients with IMN (P＜0.01).Conclusions Anti-PLA2R antibody is a sensitive serological marker of IMN.Detection for anti-PLA2R antibody might be helpful for the diagnosis of both elderly and non-elderly IMN and for the monitor of IMN disease severity.
